Purpose of personal area: controversial (e.g. personally biased) or unfinished entries and personal research in progress may not be the best for the general area of nnlab. It also allows me to use other vernaculars (languages) of my use and to create pages for my students.

Topics: Personal area allows me getting a bit out of the main topics of nnlab; though related, in addition to categories and alike notions, there could be eventually more noncommutative geometry, mathematical physics, Hopf algebras and so on here.
